<h3 id="rationale">Rationale:</h3>
<p><code>$</code> is special in double quotes, but there are some cases
where it's interpreted literally:</p>
<ol>
<li>Following a backslash: <code>echo "\$"</code></li>
<li>In a context where the shell can't make sense of it, such as at the
end of the string, (<code>"foo$"</code>) or before some constructs
(<code>"$'foo'"</code>).</li>
</ol>
<p>To avoid relying on strange and shell-specific behavior, any
<code>$</code> intended to be literal should be escaped with a
backslash.</p>
